T all whom it may cof/wcm.

Be it known that I, WILLIAM Qnnrrson, a citizen of theUnited States,residingpfat Tacoma, in the county of Pierce, State ofl/Vashington, haveinvented certain new and useful improvements inTools for RemovingDriving- Box Cellars;v and AI do hei'eby declare the following tov be afulhclear, and

exact description of the invention, such as will enable others skilledinthe art to which the cellar without in'any wayy injuring .or

' breaking any of theparts oi' the driving box.

Another object is to provide a ldevice of this character which is notonlyl simple in its construction-fy and operation, but, which can bevery `quickly and easily applied to a driving box, operated 'thereon'and removed therefrom. y

Other objects and advantages of the invention will be apparent'irom thefollowing description when' taken in connection with the accompanyingdrawings.

In the drawings: Figure lis anelevation of the locomotive driving box`looking toward the end of the axle, with my invention in appliedposition. Fig. 2isa side eleva-v tion of the saine. Fig.` 3 is ahorizontal sectional viewon the line 33 of Fig. 1. Fig.

Y l is an enlarged horizontal sectional view on the line 1-4 of' Fig. 1.Figi)V is a horizontal section on the line 5-5 'of Fig. 1.V Fig. 6 is aplan view of one of the clamps.

lt is well-known that the lubricating cellar of the ,locomotivekvdriving box becomes tightly gripped by the surrounding collar, and theordinary method of removing this cellar is to `drive the cellar from itsplace with a sledge hammer. rlhis is a process which takes considerabletime, and at the same time badly damages the cellar or collar making itnecessary to replace the collar with a new one. i

lt is theprincipal-object of the present Vinvention to provide a devicewhich willl spread the collarr open sor as to permit the byl means oitwhich thedriving cellar to `cguickly andeasily slide out of the collar,without in any way damaging or breaking thend'riving box. f

Referring' particularly to the accompanying drawings, 10 represents thedriving box and 11 'the lubricating cellar which is held between theends of the box. The opposite vertical sideso'f the box are formed withthe longitudinal parallel rods 12 which slidably engageon the sides ofthe pedestals. of the locomotive frame, as will be understood, it notbeing thought necessary to show the pedestals.

The box; spreading device vincludes a pair A of vertical side members i13 `and 11i the lower portionsoi" which;r are bent inwardly at ankobtuse 'angle as clearly. shown, these lower ends being arranged toengage the sides of the boxbetween theribs 12. f Ex-L tending inwardlyrfrom each `of the side membersl 13 and' 14C "and movable, verticallybetween the saidribs is a lu'g'l, andbelow thelug an opening u16 is'formed through the side members., Disposed;throughtheopening 16z is athreaded'bolt 17 which carries on its inner end a transversely extendinghead `518' thel outerends of which incline v-iii-"afdirection toward thepoint of attachment of the bolts 17. Engaged on these inclined ends arethe wedge blocks 19 the outer faces f of which are serrated as indicated'at 20. Links 21 are secured to the head 1S at one end and have theirother ends provided with elongated slots 22 through which are passed thebolts 23 also passed through the blocks 19. The blocks are thus capableof slidingj movement on the inclined ends of the head but `are held fromdisplacement by means of the links. Carried by the reariiace of the head18.y are the rearwardly extending pins 2t and disposed on the bolt 1'?andr provided with openings receiving the pin 241="is a plate 25, thisplate being slidably engaged on the bolt and bearing with its oppositeends against-.the rear faces of the blocks 19. rflireaded onto the bolt17 in rear ofthe plate 25 is a nut 26 which,.when screwed toward thehead 18, moves the plate 25 against the blocks 19 and causes them toslide on the inclined ends of the head thus moving them away from' eachother.

Pivotally mounted in 'the upper end of V the side member 13 is a bar 27the other end i 25 will bermoved against the blocks 19 andv ,will beforced upwardly so bers 13 and 14 are disposed on opposite f `sides ofthe boX 1() so that the heads 18V and lugs 15k are disposed between theribs 12.Y The heads 18 extend transversely between the ribs, and uponforcing the nuts 26 ina direction toward the box the plate force theserrated faces offsaid blocks into firm biting engagement with themutual ad- ]acent faces of the ribs'12.v The side members 13 and 14 arethus held nsitiononv thev boX.` Thebars-27 'and 28 are then swungdownwardly until the point 32 engagesthe inner face ofthe upper end ofthe memberl/I, it ofcourse being understood that the bars 27 and 28 aredisposed in alinement so "that they Yform in effect a'single bar..The-head 31y is then turned so that the screwBO exerts pressure to.force the upper ends ofthe side members 13 and 14 apart. The'blocksv19firmly gripping Vthe-'sides of the boX exertv outward pull so asteseparate the'sidesV of the open end ofthe Vbox andV thus*l release theCellartherefrOm. *Vlehenf the box is thusfreleased from the cellar,thefbox together with the side members 13 will slide downwardly iat thesidesl ofthe cellar, when the bars'27 and 28 engage-with the cellar,thepivotalconnection between fthe said bars that the boxV will bepermitted to spring #back into its normal Copies? of this patent may beobtained for lve cents` each, byad'dressing the "V Commissionerof'Patents, Y Washington, 11C. v v v -Y ysaid side members said drivingbox, comprising side A. members, spreading clamps carried by said sidemembers and adapted for engageinentrwith the flanges of a boX,anda'folding adjustable or breaking either the f e. f 45 1.
